Be aware that old MVS does not have CICS neither DB2 and none of IBM mainframe OS (OS390, zVM, zOS, zVSE) can be run legally on Hercules.

Thanks for sharing the resource! Using the Hercules emulator with the provided virtual machine seems like a great way to get hands-on experience with COBOL, CICS, and DB2 in a z/OS mainframe environment.
Thank you
